Abstract

The noise characteristic of an optical radiation wavelength converter based on cross-phase modulation in a single-mode optical fiber with a successively placed Mach-Zehnder interferometer is numerically analyzed. The noise characteristic at the output of the converter is investigated in order to estimate the SNR caused by the wavelength conversion at an information-transfer rate of 10 Gb/sec. The results obtained for various gains, crosstalk powers, band widths of the low-frequency filter, and information-transfer rates are considered as the input-power parameter and the low-pass bandwidth are varied. Analysis shows that optical wavelength conversion is possible at a significant SNR, which can be subsequently improved while increasing the input pump power and broadening the band of the low-frequency filter. Moreover, it is pointed out that the SNR significantly decreases at a higher information-transfer rate.
